Python 如何生成今天 0 点到现在的所有以小时为单位的时间字符串？ and ...

[Eyon]

需求：

get_today = [2020090200,2020090201,2020090202...2020090219]

get_month=[2020090100,2020090101,2020090102......2020090219]

用 datetime （ 0 点）循环加 timedelta （ hours=1 ），直到大于当前时间，然后把符合条件的的序列化成你想要的格式

@Trim21 谢谢

```python

from datetime import datetime,timedelta

now = datetime.now()
thismonth_start = now.strftime('%Y%m01')
start = datetime(2020,9,1)
while True:
if start < now:
print(start.strftime('%Y%m%d%H'))
start = start+timedelta(hours=1)
```

zfill 函数了解一下

@tairan2006 看了一下没太懂 请教一下怎么用到题主说的这个问题上呢？

@TEwrc

now = datetime.now()
prefix = now.strftime('%Y%m%d')
return [prefix + str(x).zfill(2) for x in range(now.hour)]

@tairan2006 秒啊！感谢

from datetime import datetime

time_list = []
now = datetime.now()
start_day_hour = int(now.strftime('%Y%m%d00'))
stop_day_hour = int(now.strftime('%Y%m%d%H'))
for i in range(start_day_hour, stop_day_hour + 1):
time_list.append(i)

print(time_list)
